BUILDER MECHANISM.

Application filed April 17, 1924. Serial No. 707,129.

To all whom it may concern.-

Be it known that I, ROBERT IV. GOSSETT, a citizen of the United Statesof America, and a resident of Spartanburg, county of Spartanburg,and'State of South Carolina, have invented certain new and usefulImprovements in Builder Mechanisms, of wh1ch the following is a full andclear specificatlon.

This invention relates to that well-known type of builder mechanismemployed in spinning-frames in which the ring-rail is given a transversemovement, with a gain at the end of the up movement and an equivalentloss at the end of the down movement, means being provided whereby thering-rail is given a specially-controlled traverse at the beginning ofthe winding to thereby preliminarily wind on the spindle a bunch. Thespecial object of the present invention is to provide a simplebunchforming mechanism that maybe used in connection with any of thewell-known builder mechanisms now in general use.

In the drawing I V Fig. 1 is a side elevation of so much of a buildermechanism for spinningframes as is necessary to show my invention;

Fig. 2 is a vertical sectional view line 22 of Fig. 1; i i

Fig. 3 is a vertical sectional view on the line 33 of Fig. 2; Q

Fig. 1 is a horizoutal'section on the line 4l--il of Fig. 3;

Figs. 5 and 6 are proved half-pulley In the drawing annexed, 1Odesignates the usual pivoted builder-bar which is adapted to bedepressed at intervals by the usual cam (not shown) and which carriesthe usual pick or gain-wheel 11 affixed to a shaft 12 carrying the usualworm13, this worm having constant mesh with aworm ear 1 1 affixed to achain-pulley 15. The

iihain or chains 16 from this pulley exdotail views of my imtendupwardlyover a pulley 17 and thenceto the quadrant of the usual weightedlifting-lever 18. The foregoing mechanism operates in a manner wellknown.

On the shaft 19, on which is journaled the combined gear and pulley14l15, is journaled another pulley 20 larger in diameter than theadjacent pulley 15. This pulley 20 is adapted to be clutched to thepulley on the 15 by means of a clutch consisting of a. pin

22. In the pulley 20 is mounted a thrust-pin 23, this thrust-pin beingnormally projected by a spring 24 in a direction away from theclutch-pin 21 and being so positioned in the pulley 20 that it willaline with said clutchpin 21 when the pulleys 15 and 20 are relativelyrotated.

To push in the pin 23 and thereby unclutch the wheel 20 from the pulley15, I provide a lever 25 pivoted at 25 and having an upstanding arm 27having a rounded inner face adapted to be forced against the projectingend of pin 23; the lower end of the lever 25 is turned to a horizontalposition and extends to a point near the wormshaft 12 and in the path ofa cam 26 affixed I to said worm-shaft. This cam 26 is carried by acollar 27 affixed to the shaft by a setscrew 28, thereby permitting thecam to be rotatively adjusted on the worm-shaft. It will be observedthat the rotation of the cam 26 will swing the lever 25 on its pivot 25and thus cause the upstanding arm 27 to push the push-pin 23 inwardlyfar enough to release the wheel 20 from the clutch-pin 21. It isdesirable to provide the lever 25 with a weight 29 to keep itshorizontal end in contact, or approximately in contact, with the cam 26,and, in order to permit the cam 26 to pass the lever 25, the noseportion 30 of the lever is hinged to the lever at 31 and held in itsnormal position by a spring 32.

A chain 33- extends from the large pulley 20 to a pulley 33, on the sameshaft with the aforesaid pulley 17; and another chain 34; extends from ahalf-pulley 35 of the usual form to the quadrant of the liftinglever 18.At the beginning of the operation of the machine, the clutch-pin 21 isin locking engagement with the bunch-chain wheel 20 and the push pin isopposite the upper end of the cam-arm 27. The work of building the hunchis done entirely by the chains 33 34: and the parts cooperatingtherewith, the main or service-building chain being slightly slack. Asis well understood, the first few reciprocations of the builder-bar 10give to the ring-rail the traversing action necessary to build thebunch, and thereafter thereby regularly build up the windings on thebobbin in the usual manner.

To vary the traverse during the making of the bunch, I make thehalf-pulley 35 1o tatively adjustable with respect to the pulley 33.These two pulleys are rigidly attached together by means of clamp-screwstapped into the body of pulley 33 and ex tending through arcuate slots37 formed in the body of the half-pulley. The body of the halt-pulley isset in the adjacent face of the pulley33, as shown in Figs. 5 and 6.iVith this construction, it will be observed that the half-pulley may berotatively adjusted in either direction to thus vary the'length of thetraverse of the bunches of different lengths.

The length of yarnus'ed in making the bunch is determined by theposition of the cam 26. lVhen this camQG forces the lower end of leveroutwardly, the cam-end 27 of this lever unclutches the pulleys 20 and15, to thereby 'slacken the l)iii1clibi1ilcli1ig chain 33 and thus stopthe bunch building. The rotation of the worm-gearand the pulleys l5 and20 is so slight during the bunch building operation that the push pin 23does not'pass fronrunder the cam-finger 27. By rotating'the adjustingcam 20011 the wormshaft, the unclutching action may be brought aboutsooner or later to thusvary the length of theyarn that is put into thebunch. The length of the bunch on the ring-rail. to thereby provide forbuilding spindle is varied by i'otatively adjustingthe halite-pulley,as'liei'eiiibefore described.

lVhen the bunch-building pulley 20 is re leased, the workof buildingthen falls en tirely on the chain 16. The action then continues as usualuntilthe bobbins are entirely built up, the bunch-chains 3334 beingidleduring this work of. laying the service layers on the bobbin, altho, ofcourse, the chains filth-3% continue to pay oil their pulley. .iy thetime'the bobbin is the freely running pulley 20 has been car ried aroundby its chain far enough to bring a radial shoulder 38 on a cam 39carried by the pulley 20 to a point behind a stop d0 pivotally mountedon an adjacent part of the frame and adapted to normally rest on thecircumferential edge of 02111189, said stop dropping down behind theshoulder 38 to therebv prevent the pulley 2O rotating Then when the? inthe opposite direction. operative in the usual manner, through the worm13, rewinds the main builder chain 16 upon its'pulley 15, the pulley 20will rotate backwardly with it, by reason mainly of the frictiongenerated by the clutch-pin 21 bearing on the adjacent face of thepulley 20, until the shoulder 38 strikes the stop 40. At

this point, two things happen practically simultaneously:

the clutch-pin 21 has been brought around to a point coincident with 811511111111211 1'8CGSS 111 haltpulley in each of its completed,

the thrust-pin, thus permitting the clutch pinto goint'o locking actionwith wheel and, secondly, a cam 41 carriedbymain chain-wheel 15 comesunder the stop 4-0 and lifts the same high enough to permit the shoulder38 to pass under the stop. The two pulleys are then looked togetherduring the remainder of the rewinding operation, when the mechanism isready for another building operation.
